Dr. Rabenhorst, op Dresden, has for many years been 

 engaged in the publication of European Cryptogams, a priced list 

 of which he has recently sent to me, as follows : — 



1. Herbarium Mycologicum, Centuries i. — viii., at 6 48 Thalers 



2. Fungi Europaei exsiccati, Centuries i. — xiii., at 6 78 do, 



3. Lichenes Europaei exsiccati, Ease. i. — xxxi., (Nos. i to 850) at 2J .. . . 78 do, 



4. Cladonis Europaeae 30 do. 



5a. Desmidiaceas, Century i 12 do. 



Sb. Diatomaceas, Century i 15 do. 



6. Algen Europa's, Decades i to 12, (Nos. i to 2120 at 20 s. g 141 do. 



7. Characeae Europsae exsiccatae, Ease. i. to iii. (Nos. i to 75) at 3 9 do. 



8. Hepaticse Europjes, Decades i to 44, at 20 s. g 29 do. 



g. Bryotheca Europasa, Ease. i. to xxi. (Nos. i to 1030) at 3 63 do. 



10. Cryptogamse Vasculares Europss, Ease. i. to iv. (,Nos. i to 100) at 3. 12 do. 



11. Cryptogamia — " a collection for school and home, containing exam- 



ples of all Orders and Tribes, and in the Eungi the diseases of 



cultivated plants ;" — 500 species in folio 12 do. 



(The Thaler is equal to about seventy-five cents, being exactly three shillings sterling). 



I have lately had an opportunity of examining the collection of 

 the vascular cryptogamia (no. 10 above), and of comparing his 

 specimens with our Canadian forms, and append a few notes on 

 some of the species which are common to both continents. I copy 

 Dr. E-'s nomenclature exactly ; it is near enough to that of Gray's 

 Manual to enable any one to recognise the plants. As a rule the 

 specimens are well preserved and mounted, and are amply suffi- 

 cient to illustrate the species. The four fasciculi contain in all 

 about one hundred species, many of which are illustrated by 

 several examples from various localities. 



No. 8. Botrychium simplex Hitchc. The specimens are small, but they agree exactly 

 with ours. 



No. 9. Botrychium Lunaria (Z/««.) A'a?<^. ) We have forms similar to these; both 



No. 14. Cystopteris fragilis (Z/««.) ^^r«/j. ' species are very variable. 



No. 15. Woodsia ilvensis (Swartz) K. Brown. A small specimen, but identical with 

 ours. 



No. 16. Aspidium Thelypteris Swartz. Exactly our plant. 



No. 17. Aspidium cristatum Swartz. We have forms agreeing with these, but this 

 species is much more variable in America than it is in Europe, — verging with us as well 

 towards Filix-7>ias and Goldieanum as towards spinulosum.
